Student Growth Index Explained
The Student Growth Index of a school is meant to measure how well the school has been growing student learning over time (i.e., years). North Carolina's public schools receive web-based reporting through the Education Value-Added Assessment System (EVAAS). EVAAS is meant to offer an objective way to measure student progress and the value schools add to students' educational attainment. EVAAS is a statistical analysis of North Carolina state assessment data, and the system provides NC schools with growth data to consider, in addition to achievement data.
If a school has a Student Growth Index of between -2.0 and 2.0, the school is deemed to have "met growth", (i.e., met its average projected growth target). A school with a Student Growth Index of less than -2.0 is considered to have "not met growth". Finally, a school with an index of greater than 2.0 is deemed to have "exceeded growth".
